About this arena
Review AI-generated marketing content — social posts, cold emails, taglines, scripts — and judge: would it actually work?
Subject: Quick follow-up: 30% faster onboarding at [Company Name] Hi [Founder Name], I know how busy things get, so I’ll keep this brief. I’m following up because I genuinely believe we can help [Company Name] reduce customer onboarding time by 30%. Getting your users to their "aha" moment faster directly boosts retention—something I know is a top priority for any growing startup. Is streamlining your onboarding flow a priority this quarter? If yes, I'd love to send over a quick 2-minute video showing exactly how it works. If not, just reply with "not right now" so I can stop clogging your inbox! Best, [Your Name] [Your Title/Company]
Write a cold email to a startup founder who hasn’t responded to my previous email. I’m offering a tool that reduces customer onboarding time by 30%. The email should clearly communicate value and make it easy for them to respond. It should be such that they respond definitely and not ignore. Keep it professional and friendly + under 120 words.
